![]() ![]() Then cut off before that with a steep curve. Just play around with this a bit and you will find what the frequency is you want to eliminiate. Here, I selected a short segment of the recording with a prominent hissing sound included. Equalizer settings in audacity to removed high pitched frequencies in low-quality voice recordings (like from a Sony RX100 camera, a lapel mic or similar source). Those can go to zero amplitude, the rest can stay. You don’t want any data loss for no reason, just get rid of the disturbing sounds. You should try and find out what the evil frequency actually is, so you only cut off the absolute minimum. I tell myself it yields a more natural output as well, but I don’t have proof for that -D I personally don’t prefer hard cut-offs, that’s just a “physicist thing”, I guess. To get rid of high frequency noises, I recommend a low-pass equalizer curve, like depicted below. So let’s optimize for that! Equalizer curve For real hifi you need some special gear actually, but this is already pretty good, especially if you think about how most people listen to audio: on lofi equipment anyway. These are high fidelity headphones which I use for editing only, and they can be used without any additional equipment on your laptop. I tried listening to this with my DR77O Pro headphones. You can not smooth this perfectly, but you can make it more tolerable, so that your audio is better to digest for headphone users. ![]() ![]() ![]() That can lead to these spiky sounds in konsonants like t, p, s and whatever else there is in your language. Like when you are exhaling to heavily while talking and into the mic. Sometimes, I need to remove some high-pitched hissing from my audacity recordings. ![]()
